    Title: 南非葉保健茶品開發 ─ 子計畫二:南非葉保健產品開發

    Abstract: 南非葉學名扁桃斑鳩菊(Vernonia amygdalina Del.),屬菊科喬木植物,原產於非洲和南美洲,在非洲是傳統民俗的保肝用草藥。南非葉對環境需求低,容易種植,在台灣中南部野外隨處可見,取得相當容易。南非葉在非洲當地被拿來當做保健茶飲,被認為可以降血壓、抑制癌症。
    本試驗將南非葉以40℃、60℃、80℃烘乾24小時,萃取,分別得到VA40、VA60、VA80萃取物,由結果得知,VA40抑制自由基效果較佳,是由於VA40樣品的總多酚類化合物與總黃酮類化合物含量較高,但是 VA40、VA60、VA80皆具有抑制細胞黑色素合成之活性,我們認為VA40、VA60、VA80並非都是相同作用路徑,VA80雖然總多酚類化合物與總黃酮類化合物含量較低,但在較高的溫度乾燥下,似乎產生其他抗氧化成分,不但可以有效減少細胞內氧化壓力,也可以抑制UVA誘發細胞內GSH含量增加,並進一步減少細胞黑色素。
